| Research Abstract |
A multi-sensor buoy, a drifter attached with a GPS wave-sensor and water-quality sondes, was developed to observe directly the impacts of wind variation on the vertical distributions of nutrients and phytoplankton in the epipelagic ocean through the air-sea interfacial processes mainly caused by wind waves. In-situ data of the epipelagic ecosystem at the surface and subsurface layers obtained continuously by the multi-sensor buoy promoted effectively validations of the lower-trophic-level ecosystem model and modifications of schemes of the interfacial fluxes and mixed layermodels, consequently contributed to the accuracy improvement of the ecosystem model.
